Outdoor Water Saving Tips

Tips for Conserving Water Outside of Your Home

Lawn Care

Laying new seed or sod?
New sod and seed may be watered within restricted hours. To obtain a special
permission, call District Office at 265-2048.

How much water?
Lawns need only 25 millimeters (1 inch) of water per week, including rain.
Longer, infrequent watering will help to develop deeper, healthier roots. Keep
your grass two to two and half inches high and you will help the soil retain
moisture and reduce evaporation from sunlight and wind.

Aerate your lawn
Aerating promotes grass roots to absorb all the natural moisture that is
available. Aerating also lets air flow into the soil and provides the grass
roots with oxygen. You can aerate simply by puncturing the lawn with a
gardening fork or by renting a powered aerator. Check with your tool rental
equipment dealers or aerating service companies for further information.

De-thatch you lawn
Thatch is the layer of organic matter that forms between the blades of grass
and the soil. A thin layer of thatch can be beneficial, preventing evaporation
of water from the topsoil. Too much thatch can be harmful and can rob the
roots of the oxygen and water needed for healthy growth. Remove the thatch
from your lawn at least once a year, using a rake, a thatching attachment on
your mower or a thatching machine.

Fertilizer
A well-balanced soil that is properly watered should not need fertilizer.
Donít give your lawn too much fertilizer, as it might outgrow its soil
limitations and watering regime. Avoid applying fertilizer, herbicides or
pesticides during the dormant period.

Lawn Alternatives
Consider replacing some areas of lawn with low-growing ground covers or herbs.
Another alternative is to cover parts of your garden with hardscape made from
natural or synthetic materials, such as flat rocks, flagstones, concrete
asphalt or compact gravel.

Mulching
Mulching around plants reduces the number of weeds (which compete for water)
and conserves soil moisture and moderates soil temperatures. The recommended
depth for mulches is 2 to 4 inches (5 to 10 cm). Good mulches are straw, leaf,
bark, gravel or wood chips.

Flower and Vegetable Gardens

About 70 to 80 per cent of all plant problems are directly related to
incorrect watering.

Water around the base of plants slowly and deeply - moistening the top 4
to 6 inches of soil - at least once a week. Light, frequent watering is
harmful because it encourages shallow root growth and enhances germination of
weed seeds. You can check the soil wetting depth with a screwdriver or stake.

Water plants early in the morning to avoid evaporation from the sun and
wind. Watering in the middle of the day increases the amount of water lost to
evaporation by as much as 40 percent. Conversely, watering in late evening
lets droplets remain on leaves, which can promote plant diseases.

Consider installing drought-tolerant native plantings. A drought-tolerant
plant can survive with very little, if any, artificial watering or irrigation
once it is established. Natural rainfall is usually enough for these plants,
if theyíre growing in the right habitat (i.e. one similar to their natural
habitat), and they can usually survive weeks of dry weather.

Plants with grey, fuzzy, waxy or finely divided leaves are also considered
drought-tolerant. Perennials like daylilies, flax, pinks, bellflowers and
peonies thrive under dry conditions. Annuals like cosmos, sage, mallow and
California poppies are also drought-tolerant and provide season-long color in
your garden. Check with your garden centre for further suggestions.

Trees and Shrubs

When watering trees and large shrubs, water around the drip-line of the
tree (area below the branches where water drips from the leaves) - not at the
trunk. A great way to water trees is to use milk or water jugs. Fill with
water and poke small holes about 8 in the bottom of each. Place these around
the drip line of each tree. The water seeps out slowly into soil near the
roots, where the tree needs water the most.

Avoid heavy direct watering by hose, which can wash away soil, exposing
the roots to pests and disease, and making shrubs and small trees more
susceptible to blow down.

Keep turf at least two feet from the trunks of young or newly planted
trees as it will compete with the trees for water. Consider applying mulch in
this area.

General Outdoor Water Saving Tips

Weed regularly. Weeds compete with your plantings for moisture.

Consider installing a Micro/Drip irrigation system. Micro/Drip irrigation
systems use low-water-volume irrigation components (under 20 gallons per
hour), at low pressure (under 25 psi) to deliver a precise amount of water to
the root zone of plants. These systems can be tailored effectively to
individual plant and garden needs. During even the most stringent water
conservation measures, micro and drip irrigation systems can be used to water
flowers, trees, shrubs and vegetables.

Make sure hoses are in perfect condition. A hose delivers 27 litres of
water per minute so a leaking hose or coupling can add up to significant water
waste.

Use nonporous containers like glazed pots, as they are more efficient at
retaining water. Also, use larger containers (pots 10 inches (25 cm) in
diameter and larger) as the larger the volume of soil, the slower it dries.
Nest smaller pots inside larger ones and insulate the space between the pots
with potting soil. This will keep the roots cool and will slow down
evaporation.

Consider collecting and recycling water by installing rain barrels outside
of your home. The average house roof in our region can collect 272 litres of
rain (60 gallons) on each nine square metres of roof, for every 1 inch of
rain. Installing rain barrels at the downspouts of you eaves troughs is a
great way to collect rainwater to use on you lawn or in the garden during our
dry summer months. Make sure it has a secured lid to prevent children gaining
access; this also will discourage breeding mosquitoes, prevent contamination
and keep out wildlife. You will also need an overflow attachment and hose
attachment for watering. Please visit our web site for more information on
where you can purchase a
rain barrel

Wash your car or boat with a bucket of water and soap and then rinse it
using a hose with a shut off device. Do not leave hose running or left
unattended.

Clean your sidewalks and driveways with a brush or broom. If it is
necessary to use a hose, make sure it is equipped with a shut off device.

Adjust irrigation systems and/or sprinklers so that water does not run
down driveway, sidewalks or street. This is considered a waste of water and is
in direct violation of the water conservation bylaw #3061.

If water is needed for a restricted use, consider a bulk purchase from a
supplier who uses a well or water from outside the Greater Victoria Drinking
Water System.

Cover the swimming pool. An uncovered swimming pool loses one inch of
water per week. Also, check regularly for cracks and leaks, and backwash only
when necessary.

Do not water on windy days, cool, overcast or rainy days. Consider making
your irrigation system more water efficient by installing a rain shut off
device that will automatically turn your system off when it is raining.
